  The FSUSB30 is a low-power, two-port, high-speed USB 2.0 switch. Configured as a double-pole double-thhrow (DPDT) switch, it is optimized for switching between two high-speed (480Mbps) sources or a Hi-Speed and Full-Speed (12Mbps) source. the FSUSB30 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7pF. the wide bandwidth of this device (720MHz), exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk minimizes interference.
The FSUSB30 contains special circuitry on the D+/D- pins which allows the device to withstand an overvoltage condition when powered off. This device is also designed to minimize current consumption even when the control voltage applied to the S pin, is lower than the supply voltage (VCC). this feature is especially valuable to ultraportable applications such as cell phones, allowing direct interface with the general purpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers. |
